XEmacs' desktop icon greyed out in 21.2

Maybe I should have reported this much earlier, but perhaps I got used to that odd behaviour ... Nevertheless, finally: Since a few beta versions of 21.2, the desktop icon of XEmacs is displayed greyed-out on my window manager (i.e. not that usual colored red, yellow and white style). Same for dtwm and mwm window manager. I don't remember exactly in which version this occured for the first time, but it definetely happens when I start the latest 21.2-b19 (compiled from the tarballs) and on the other hand everything's ok when I start that old 21.2-b11 binary I still have (also compiled myself). As I haven't built each and every version in between, I can't determine when I saw this first. Surprisingly, when opening the file <installdir>/lib/xemacs-21.2-b19/etc/xemacs-icon.xpm within XEmacs and call "M-x xpm-mode" afterwards, the XPM image is displayed as expected at the top of the buffer. Perhaps somebody can shed a little light on this? OS is AIX 4.3.2, Installation file attached below. (BTW, when talking about the Installation file: It always complains that "Motif dialog boxes cause problems on AIX 4.3 and higher". I've never seen any of them ... What problems are these?) TIA for your help! (See attached file: Installation) --- Markus Alt IBM Laboratory Boeblingen, Germany
